Frontios Part 4

The Doctor and his companions must stop the Gravis and his Tractators from using a gravity motor to control planets and spread their influence across the galaxy.

The Doctor, Tegan, and Turlough find themselves on the planet Frontios, where they encounter the Gravis and his Tractators. The Gravis has been using a gravity motor to control the planet and its inhabitants, and plans to use it to drive Frontios through the galaxy, stealing and plundering wherever they go. The Doctor and his companions must navigate the Tractator lair, the research room, and other locations to stop the Gravis and his plans. Along the way, they meet various characters, including Norna, Cockerill, and Range, who aid or hinder their progress. As the story unfolds, the Doctor and his companions discover the true nature of the Tractators and the Gravis's plan, and they must use all their skills and ingenuity to stop him and escape from Frontios.

Act 1

The episode opens with the Doctor and Tegan as captives of the Gravis, who details his plans for the Operations Centre and his awareness of the Time Lords. Simultaneously, the colonists face internal struggles; Norna fends off an attacker and is later rescued by Cockerill, who is organizing an armed resistance against the Tractators. The Doctor, ever resourceful, attempts to gather information and subtly mislead the Gravis, even using Tegan as a prop in a feigned malfunction. Captain Revere dies, highlighting the Tractators' ruthlessness. Range, lost in the tunnels with Brazen, eventually encounters Turlough, who joins their desperate search. The Doctor inspects the tunnelling machine, deducing the Gravis's use of gravitational engineering to manipulate Frontios. Plantagenet is forcibly linked to the machine, prompting the Doctor to secretly advise him to trust his instructions. The tension escalates as Range is captured by a gravity beam, and a chaotic rescue attempt unfolds in the Operations Centre, where Brazen saves Turlough from a Tractator beam, but Tegan chastises Turlough for disrupting an unseen plan. This act establishes the immediate peril, the antagonist's full ambition, the fragmented resistance efforts, and the Doctor's initial, indirect maneuvers to understand and counter the threat. The stage is set for a direct confrontation within the Tractator's Lair.

Act 2

The second act plunges into the direct confrontation within the Tractator's Lair. The Doctor, Tegan, Turlough, and Brazen arrive, interrupting the Gravis's demonstration. The Doctor initiates his counter-plan by pulling a crucial linkage from the tunnelling machine, which temporarily stuns the Gravis and disorients the other Tractators. This moment of vulnerability allows Norna, who had been gagged and tied, to free herself in the Research Room, signaling a broader shift in the colonists' fortunes. However, the victory comes at a cost; as the Doctor attempts to free Plantagenet, Brazen is tragically assimilated by the machine, sacrificing himself to ensure the Doctor and Turlough escape. Following this harrowing escape, the Doctor, Turlough, Plantagenet, and Tegan regroup in a natural cave, where they synthesize their knowledge. Turlough recalls the critical secret: the Tractators are inherently harmless burrowing creatures, drawing all their power and menace from the Gravis. This revelation provides the Doctor with a clear path to victory. The urgency intensifies as an Orderly is captured, and Tegan discovers the partially reassembled TARDIS. The Gravis finds them, intending to use Tegan as a new driver, but she escapes into the TARDIS. Inside, the Doctor reveals his audacious plan: he will trick the Gravis into reassembling the TARDIS, thereby isolating and neutralizing the creature. The Doctor then engages the Gravis in a deceptive negotiation, luring him into the TARDIS. Once inside, the Doctor manipulates the Gravis into activating the TARDIS reassembly process, using the creature's own gravitational powers against him. The TARDIS dramatically reassembles, and the Gravis collapses, rendered inert and harmless by his isolation from the other Tractators.

Act 3

With the Gravis defeated and the TARDIS repaired, the narrative shifts to the aftermath and resolution on Frontios. Plantagenet and Range, now fully recovered and back in uniform, reflect on the Doctor's bravery and the creature's harmless state. Turlough collects the hat stand, a symbolic piece of the TARDIS. The TARDIS materializes, and the Doctor confirms the Gravis is safely deposited on the uninhabited planet of Kolkokron, where his gravitational powers are now harmlessly directed at rocks and boulders. Plantagenet expresses the profound realization that humanity, the last of its kind, is now truly alone in the universe but in good hands. The Doctor, adhering to Time Lord protocols and his own pressing repair work, declines an invitation to stay, offering Plantagenet the hat stand as a simple, yet meaningful, farewell token. The Doctor, Tegan, and Turlough enter the TARDIS, which dematerializes, leaving the Frontios colonists to rebuild their lives free from the Tractators' terror. Once inside the TARDIS, the Doctor sternly warns Tegan and Turlough about the severe consequences if the Time Lords ever learn of their intervention on Frontios, emphasizing the strict policy of non-intervention. However, their relief is short-lived. The TARDIS engines begin to malfunction again, making a strange noise and accelerating uncontrollably. Despite the Doctor's attempts to dismiss it, the TARDIS judders violently, and they realize they are being pulled by an unknown, powerful force towards the middle of the universe, setting up a new, immediate threat and a fresh adventure.
